Application filed October 15, 1 925.,Seria1 N'o. 62,598.'

An object of the presentinvention is tot provide a combination tank heater and house heating boiler, so arranged that eithenthe boiler or the house system may be optlonany time, and the full heatrected into the other.

A further object of the invention is to provide a system of this character by which the cutout may be effected easily and quickly.

A still further object of the invention is to provide a unique type of water heating unit divided intoa pair of heatin chambers, which may communication witheach other to form a single chamber.

Further objects of the invent-ion are to provide means for accomplishing the above noted results without materially adding to the cost of the heating unit, and without in any way affecting its efliciency.

With the above noted and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter set forthand pointed out in the claims. The invention may be more fully understood from the following description in connection with the accompanying drawings, wherein-.

Fig. 1 is a diagrammatic view of a hot water heatincr system embodying the invention, parts o the heat generating unit being broken away and in section for clearness.

Fig. 2, is an enlarged sectional detailthrough the topof the heat generating unit.

Fig. 3 is an enlarged view in transverse section on'the line 33 of Fig. 1.

Fig. 4: is a view similar to Fig. 1, showing the house heating system out out of the circuit.

Referring with particularity to the drawings, reference character 10 indicates a conventional type of furnace equipped with the usual fire box ll, and formed with a domelike water heating chamber 12 surroundin the fire box. The, chamber 12 is divided into two compartments by partition 13 of general U-shape. One of the compartments defined by the partition13 is connected with a take-0E pipe 14; to a tank 15. taps the upper end of the chamber, and the return lead 16 from the tank enters the lower end of the chamber 12 in the usual manner. The other doinpartment of the be optionally placed ,in'

chamber 12 is connected at its upper end to an off-take pipe 17 conveying hot water to a system ofhouse heating radiators 18, T

the return being through pipe 19 to the lower end of the chamber 12. I

I It will be seen that in normal operation, chamber 12 provides two similar water heating compartment, one of which supplies the tank 15, and the other of which supplies the house heating radiators. v

In order that I may optionally cut out either the tank or the radiator system, and

still utilize in so far as possible, the heat generated within the fire box 11, I form a threaded opening 20 in the partition 18 at the top of the chamber 12, said opening being closed by screw plug 21. This plug is accessible through theopenings 22, 23 in the top of the chamber into which the pipes 17 and 14- are screwed. It is to be noted from Fig. 3 that thepipes 16 and 19 also enter the rear end of the chamber fairly close together, and closely adjacent the partition 13. The partition may be provided with an additional plug 25, so that by removing the plugs, free circulation through the entire chamber 12 is had.

4' shows an arrangement in which the house heating circuit has been eliminated, and all of the heat is utilized for heating water in the tank 15. It will be seenthat the plug members 21, 25 have been. removed,that the pipes 17 and 19 have been unscrewed, and the openings in the chamber 12 which receive them, plugged up as indicated at 2.6; It will thus be evident that the operation, of cutting out-either the tank or the radiator system is a very simple one, it being necessary merely to unscrew two pipes and two plugs, and to plug up the openings from which the pipes were removed.

While the embodimentof the invention illustrated is a preferred one, it will be evident that various changes and alterations might be made in the general form and arrangement of parts described, without departing from the invention. Hence I do not wish to limit myself to the details set forth, but shall consider myself at liberty to make such changes" and alterations as fairly fall within the spirit and scope of the appended claims. U

I claim- 1. A heating unit including a fire box and a. substantially dome shaped water heating chamber surrounding the fire box, a substantially U-shaped' vertically disposed partition dividing the Water heating chamber into tWo compartments, said partition hav ing openings therein near its upper and lower ends and plugs for closing said openings.

2. A heating unit including a fire box and a substantially dome shaped Water heating chamber surrounding the fire box, a substantially U-shaped vertically disposed partition, dividing the Water heating chamber into two compartments said partition having openings therein near its upper and lower ends and plugs for closing said openings, inlet and outlet pipes entering the compartments at points closely adjacent the holes therein, whereby When said pipes are removed handholes Will be provided for permitting the removal or replacement of the plugs.
